Issued 2026-10-23

Nothing significant. Questions worth asking about Organization & Key-Person Risk, Security & Reliability Posture.

106 checks ran across 6 assessable dimensions. 1 finding is worth checking first. 6 findings, each with evidence. One dimension cannot be assessed without an acquirer.

Worth checking first

Borehole's proprietary scoring is calibrated across hundreds of repositories. Each finding here reads significant, but its check has not yet held up often enough in that calibration to rate significant on its own. If one holds when someone checks it, it is significant.

  • 03.5 The contributor who wrote three-quarters or more of this has not committed here for more than a year
strong adequate significant findings not assessable from a repository
Provenance disclosure does not affect any rating
0% of the code standing today was written in AI-declared commits
0% of lines still in the tree 0 of 9,003 0% of lines ever added these differ when early hand-written code has since been replaced
0/368 commits declaring an agent
confidence: moderate
  • 12% of non-merge commits carry any trailer at all
  • low trailer coverage: the convention may not be in consistent use
  • no widespread author/committer date divergence
  • deep scan blamed 56 of 56 counted files
741,999 lines excluded as lockfiles, vendored or generated.
This is a lower bound. It counts what the repository declares. Undeclared AI authorship is invisible here, and a single rebase removes the trailers this rests on. Absence of a declaration is absence of disclosure, not absence of AI authorship.

01.25

1 base image floats: no version, or `latest`

adequate

1 of 1 `FROM` lines in product Dockerfiles name an image without a version, or with `latest`. Each build pulls whatever the registry serves that day, so the image that ships can change without a commit, and last month's build cannot be reproduced. Pin a version, or a digest.

Evidence
Dockerfile Dockerfile:1 — base image without a version
Respond to this finding

Your response is published beside the finding, not instead of it. A finding you can argue with is the point — and a wrong one is calibration data we want.

An owner's response is removed only when it is unlawful, impersonates someone, publishes personal data or a credential, or is not about the finding. Disagreeing with the report is never a reason. To report a response, or to reach us about one, write to takedown@borehole.dev.

03.1

Bus factor 1: the history is concentrated in one contributor

adequate

In the whole history, one contributor authored three-quarters or more of 324 non-merge commits among 34 authors; across all history, three-quarters or more of 324. In a project with 34 recent contributors and 8 years of history, that is a question about one person's role rather than a fragile team — but it is the question to ask.

Evidence
git shortlog -sn whole history: top author three-quarters or more of 324 commits; bus factor 1; 34 authors

03.4

82% of contributors committed exactly once and never returned

adequate

28 of 34 contributors made a single commit. That is the signature of a codebase that is hard to join: people arrive, land one change and do not come back. It matters after an acquisition because putting new engineers on this system is the first thing anyone will try to do.

Evidence

03.5

The contributor who wrote three-quarters or more of this has not committed here for more than a year

adequate worth checking first

One person authored three-quarters or more of 324 commits and has not committed here for more than a year, while the repository has kept moving. The concentration figure alone would not show this. Whoever is changing this code now is not the person who wrote most of it, which is the situation an acquirer is usually told they are avoiding. The history shows only that no commits of theirs landed here, not why.

The check that found this reads significant, but it has not yet held up often enough in Borehole's calibration to rate a finding significant on its own. If it holds when someone checks it, this finding is significant.

Security & Reliability Posture

05 · adequate · ratings ↑
05.2

None of the standard security guard rails are configured

adequate

There is no disclosure policy, no automated dependency updates, no named code owners and no pre-commit configuration. None of these is load-bearing on its own. Their collective absence says that security posture here is whatever the current team happens to remember to do, which is not a posture that survives the team changing.

Evidence
guardrail-scan checked 5 kinds of guard rail across 57 tracked files; 0 present

05.6

1 Dockerfile runs the application as root

adequate

No USER instruction switches away from root, so the process runs with full privileges inside the container. It is a one-line fix and an ordinary expectation, which is why its absence is worth asking about: it usually says more about whether anyone has reviewed the deployment than about this container specifically.

Evidence
no-USER-instruction Dockerfile — runs as root

Not rated: structurally not assessable from a repository. What a person adds here.

Check it on the running system

2 checks against the running system follow from the findings above: what a buyer's engineer will try, how to run it first, and what to have ready. A paid survey of this repository includes them. See the tiers.

A paid survey of a public repository is also reviewed: a language model reads each finding against the code and withdraws only findings it judges the code contradicts, each listed with its reason. The review is a language model's reading of the findings against the code, and it can be wrong. It never adds a finding, never raises a band, and never removes a finding from a proven check or an advisory that affects the surveyed version.

What a person adds

The survey reads what the repository can show. The code cannot settle these questions, and on them this report states nothing. Each says where its answer lives: your own engineer, the company, or an assessor you choose can settle it. Questions marked measured open with something this repository shows.

Fit with the Acquirer

07 · none coverage

Not rated: structurally not assessable from a repository.

  1. This is primarily a Go codebase. Does your engineering organisation already run Go in production, or would this be the first? 07.1
  2. The bulk of this system sits in pkg/, internal/, logos/. Which of your existing systems would each of those have to absorb or replace? 07.10
  3. The repository carries deployment configuration (Dockerfile). Does that match your deployment and on-call model, or does it need rehosting first? 07.2
  4. What is your tolerance for the findings above remaining unaddressed for the first two quarters after close, given everything else that will compete for this team's time?
  5. Which of these systems duplicate yours, and which get retired? Answer lives in: Your architecture07.11
  6. What will integration cost, and in what order? Answer lives in: The engagement07.12
  7. Where does the team land in your organisation, and who reports to whom? Answer lives in: Your org design07.13
  8. Are there earn-outs, retention packages or contractor IP to assign? Answer lives in: Deal terms07.14
  9. Do customer contracts limit hosting, regions or vendors? Answer lives in: Customer contracts07.15

A human assessment is Borehole's own paid service, €12,000+ (total price is determined per engagement; travel billed at cost). It is not independent of this report: the same business produced both. It is a separate contract, with its own scope, terms and reliance.

Embed the badge

Tied to this commit and this date, and it fades after 90 days — an honest badge is one that expires. A repository with significant findings gets a neutral "read" badge rather than a red one: the library is where the range is visible, not someone else's README.
